What function is that?  What does it do with the oid?

You don't mention what language and interface you're using but it
sounds like C and libpq.

You could rely on the knowledge that Oid is

typedef unsigned int Oid;

and use strtoul() to convert the char * to an unsigned int.  Another
way, if you're using 7.4 or later, would be to issue the query with
PQexecParams() and request binary results.  I think you'll have to
deal with byte order issues in that case.

This is off-topic for pgsql-admin; pgsql-interfaces or pgsql-general
would be more appropriate.
